+To update to the newer version of the Unicode standard, the latest
+released version of the UCD can be found here:
+
+  http://www.unicode.org/Public/UCD/latest/
+
+To build the utf8data.h file, from a kernel tree that has been built,
+cd to this directory (fs/unicode) and run this command:
+
+	make C=../.. objdir=../.. utf8data.h.new
+
+After sanity checking the newly generated utf8data.h.new file (the
+version generated from the 11.0.0 UCD should be 13,834 lines long, and
+have a total size of 1104k) and/or comparing it with the older version
+of utf8data.h, rename it to utf8data.h.
+
+If you are a kernel developer updating to a newer version of the
+Unicode Character Database, please update this README.utf8data file
+with the version of the UCD that was used, the md5sum and sha1sums of
+the *.txt files, before checking in the new versions of the utf8data.h
+and README.utf8data files.
